azure-policy parser: allow overriding the column-width limit

[anakrish]

Some Azure Policy JSON documents contain very long lines — ARM template expressions with deeply nested if()/concat() calls can easily exceed the default 1024-column lexer limit.

Add Parser::new_with_max_col() and corresponding parse_policy_rule_with_max_col() / parse_policy_definition_with_max_col() entry points so callers can raise the limit when needed. Also bump ExprParser's own default to 65536 since template expressions are routinely thousands of characters wide.

Pull request overview

Adds configurable lexer column-width limits to the Azure Policy JSON parser so very long single-line policy documents (e.g., deeply nested ARM template expressions) can be parsed by allowing callers to raise the default 1024-column limit.

Changes:

• Add Parser::new_with_max_col() to optionally override the lexer's max_col for Azure Policy parsing.
• Add parse_policy_rule_with_max_col() / parse_policy_definition_with_max_col() public entry points and route existing APIs through them.
• Increase ExprParser’s internal lexer max_col to 65536 to better handle large template expressions.
